Destroying Variables In Javascript - Destroying variables in javascript

how do you delete the contents of a variable in javascript? Any ideas?

This is how I would do it. There might be a proper function that does it but this method works perfectly well.

HTML
<script type="text/javascript">

// Set variable

colour = "blue";

// Delete its contents

colour ="";

</script>

ok I have javascript in a loop and the variables for each loop is clashing.eg

first loop
var countdown = "2"
first loop

second loop
var countdown = "5"
second loop

Is there any way in javascript to do this

x=0

first loop
x++
varcountown x = 1
first loop

second loop
x++
varcountown x = 5
second loop


the x results the variable name to be listed

varcountown1
varcountown2
varcountown3
varcountown4
varcountown5

so they dont clash is this possible? electriic ink?

I am fairy sure the answer is no. Someone else might be able to say though; I don't know lots about Javascript.

I dont really understand what are you trying to do but its possible that you give each variable a different name so that they dont clash and product different values for different var..

I cant do that because the script is in a php loop

Perhaps you could describe what you are trying to do so we can understand the logic you are trying to get behind by using 2 loops. I don't really understand why you are using 2 loops to do a countdown.

If it is in a PHP loop you can still change the name of the Variables.
I did not get the reason why cant you have different names for the variables.

Also if you dont want them to clash put / insert them in a array and then check if the value exists or not in the array.
If it does then do something and change the value that will now be inserted.
If it does not then insert it making things unique.
